Abstract

PURPOSE: To enable the use of a switching regulator for an AC voltage and for a DC voltage even if the difference between the voltage is large, by equalizing the chopping frequency of a chopper circuit to the oscillation frequency of a DC/DC converter.
CONSTITUTION: The chopper circuit 1 and the DC/DC converter 2 are connected in series with each other. The not-yet-rectified high-frequency rectangular voltage (e) produced on the secondary side of the transformer T of the DC/DC converter is integrated by an integration circuit 5 to generate a triangular wave of small amplitude to equalize the chopping frequency to the oscillation frequency of the converter. Thus, the switching regulator operates properly even if an input voltage Vi fluctuates greatly. Therefore, the switching regulator can be used for the AC voltage 100V and for the DC voltage 23V. Even if a load RL changes, the oscillation frequency is almost constant because of the properties of the DC/DC converter. Since no pulse generator is needed, the construction is simplified.
